I just bought a PM200-13C & was adjusting the output voltage. In a
careless fashion, I turned the one pot I saw without marking it,
hoping that the lacquer would break so I could see where the pot was
originally set. Unfortunately, the lacquer broke off the pot
completely & the output voltage stayed put. I then saw the pot behind
it, which adjusts the output quite nicely. Now I want to set the
first pot back, but can't figure out what its function is. I figured
it might be the overvoltage protection, but the ps trips out at 19.2V
regardless of pot setting. Over current maybe? Any ideas?
Datasheet for ps is he

I know I was being careless, please don't grill me, I'm just looking
for a little help.

Thanks,
Steve
